Detailed Guide to Avoid Altitude Sickness in Cusco, Peru

Visiting Cusco and the surrounding Andean region is an unforgettable experience. However, the high altitude can catch many travelers off guard. From preparing your body before your trip to acclimatizing when you arrive, this guide covers everything you need to know to make the most of your visit while avoiding altitude sickness in Cusco, Peru!

How to prepare for high altitude in Cusco

Before your trip, use these tips to help your body better handle high altitudes:

  • Improve your aerobic fitness beforehand: Activities like running, swimming, or hiking improve cardiovascular efficiency, helping your body use oxygen better in high-altitude conditions.
  • Build strength: Focus on leg and core exercises to prepare for treks like the Salkantay, which require endurance.
  • Stay hydrated: Start hydrating a few days before your trip, as higher altitudes will require your body to use more water.

Cusco altitude: what to expect and symptoms of altitude sickness

At 3,400 meters (11,152 feet), Cusco is significantly higher than most travelers are accustomed to. Altitude sickness can strike quickly, especially if you fly directly to Cusco from a lower elevation. Symptoms often include:

  • Headaches
  • Dizziness
  • Nausea
  • Fatigue
  • Shortness of breath

Acclimatization Tip: Arriving by bus from lower elevations (like Arequipa or Puno) allows for a gradual ascent, reducing the risk of altitude sickness. If you fly directly, take extra precautions during your first 24–48 hours in Cusco.

Acclimatizing in Cusco vs. Sacred Valley

Cusco isn’t your only option for adjusting to the altitude. The Sacred Valley is located at 2,800 meters (9,186 feet), which is notably lower. For many travelers, spending the first day or two on a Sacred Valley tour or on a Machu Picchu tour (lower altitude at 2,430 meters/7,972 feet) helps the body adjust much better.

Altitude sickness prevention tips for Cusco

When you arrive in Cusco, take it slow. Here’s how to adjust smoothly:

  • Drink coca tea: A traditional remedy, coca tea is widely available and can help ease mild symptoms
  • Hydrate: The dry mountain air increases water loss, so drink plenty of fluids.
  • Rest and take it easy: Minimize physical activity during your first 24 hours.
  • Eat light meals: High-carb foods are easier to digest and provide energy.

Summary

The high-altitude conditions in Cusco require preparation, but with the right strategies, you can enjoy everything this spectacular region has to offer. From exploring the Sacred Valley to trekking to Machu Picchu, acclimatizing properly will ensure your experience is safe and enjoyable!
